Game Engine Beta v0.0.5

In version v0.0.5, I ported the game engine from OpenGL to Apple's Metal API.

Initially, I planned to keep working on the 3D soccer game using v0.0.4 of the engine. However, I decided to port the engine once I saw an Augmented Reality demo. I realized that Augmented Reality (AR) is the future of gaming and it may be a good idea to have this feature available in the engine. However, the AR framework only works with the Metal API; it does not support OpenGL.

To be honest, my goal was to port the engine to Metal in a year or two. I was not planning to port it so soon. Part of it was that I feel I'm still learning Game Engine development and didn't want to overwhelm myself. The other reason was that porting a Game Engine from one API to another is not an easy task. When I saw the AR demo, it was the push that I needed.

To my surprise, porting the engine to Metal was quite simple. In less than two weeks I had ported the major components of the rendering engine. I also became aware of some misconceptions I had with computer graphics and OpenGL; essentially with Normal Maps and Shadows. Metal is so simple to use that it highlighted some errors I was making with OpenGL.

Overall, I would say that the porting took about a month to complete. It does not include the time it took to learn Metal, which it should take you about a week; assuming you know computer graphics.

Here is a video showcasing the 3D soccer game with Metal. In my opinion, it looks better than when I was using OpenGL, but then again I am using better 3D models.

This video shows the game engine using the Metal API for its rendering operations. The game engine no longer uses OpenGL.

So, the engine now runs entirely on Metal.

Goodbye OpenGL

Hola, Metal

Thanks for reading.
